Up until a few hours back, Viber, the popular VoIP service app was available for Android, BlackBerry, iOS, Windows Phone, and other mobile operating systems only. The good news is that Viber users can now make calls from Windows and Mac desktop as well.

Yes, Viber today released desktop client for Windows and Mac operating systems. PC and Mac users can now head over to the download page to begin downloading the setup.

For those who don’t know what Viber is, it’s a cool service that offers free text, photo message, and video calling for free. With the help of desktop client, you no longer need to turn up to your smartphone to make a call or send text. The other cool thing is that you can also transfer calls between your PC and mobile with a click.

The best thing about Viber is that you don’t need to register an account with Viber to use this free service. Viber lets you make call and text by using your existing mobile number, which also means that you can’t use this service if you aren’t willing to share your contact with Viber for privacy reasons.

The other downside is that in order to activate Viber on your desktop, you must first install Viber app on your smartphone. Even though Viber supports all major mobile operating systems out there, including Android, Bada, BlackBerry, iOS, Windows Phone, and Symbian, if in case you’re using a mobile that doesn’t support installing apps, you can’t activate and use Viber.
